BERLIN — German Chancellor Angela Merkel called Sunday for tougher European and global rules on data protection amid fallout from recent revelations about U.S. surveillance programs.

Merkel pledged that Germany will take a "very strict position" in ongoing talks on European Union-wide data rules. Germany will push for those rules to oblige companies such as Google and Facebook to tell European countries who they share data with, she told ARD television.
